Description

Aluminum frame of a combined photovoltaic module

technical field

The utility model relates to a frame, in particular to a combined aluminum frame of a photovoltaic module.

Background technique

At present, traditional energy is limited in non-recyclable use, heavy pollution, low utilization rate, damage to the ecosystem, and high cost. New energy represented by solar energy and wind energy just makes up for these deficiencies. More and more countries use new energy As an important way to achieve sustainable development, solar energy, as an inexhaustible green energy, has attracted more and more attention from researchers.

The application of solar energy usually converts the absorbed sunlight energy into electrical energy through solar panels. Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a photovoltaic effect that uses solar cell semiconductor materials. Solar photovoltaics generally have solar panels. Wide and direct composition, the peripheral seal of the component is very important to the reliability of the component. First, the important raw material of the component-tempered glass is a high-stress material. Second, the peripheral seal also plays a waterproof role to prevent water vapor from contacting the EVA layer in the laminate, thereby affecting the life of the EVA and reducing the life of the component. Therefore, a regular photovoltaic solar module needs a peripheral seal. The currently known peripheral packaging of photovoltaic modules has the following forms, which are conventional aluminum profile packaging, single-sided adhesive strip packaging or frameless components without packaging materials;

At present, the best peripheral sealing is to use aluminum frame. Solar aluminum frame structure refers to the aluminum alloy profile fixing frame for photovoltaic solar panel components, which is used to fix and seal solar cell components, enhance component strength, prolong service life, and facilitate transportation and installation. . Solar module frames generally include long frames, short frames and aluminum profile connectors, but using aluminum profile connectors to connect the long frame and short frame is more complicated, the installation is not convenient, the connection is not tight, and the sealing is not good. The conventional aluminum frame on the market today has a high linear density, causing the weight of the aluminum frame to account for nearly one-fifth of the weight of the entire module, and the smaller the module area, the greater its specific gravity. At the same time, another side effect of high linear density is high cost. Secondly, the space occupied by conventional aluminum frames for small components is relatively large, and a large amount of space is required to carry multiple components. Finally, multiple small components occupy a large area of space when used at the same time, and it is not easy to adjust to a suitable angle against the sun. In addition, Before the aluminum frame is installed on the component, multiple processes are required, especially the processing of mounting holes, water outlet holes and grounding holes. Due to the different design drawings of various manufacturers, different punching molds must be designed for the same type of component, resulting in It is very wasteful, and because the mounting hole and the component are integrated, when the component is installed, the components of different manufacturers often need to design different bracket drawings, which greatly affects the installation efficiency and product versatility; thus, the design and development Finding a combined photovoltaic module frame that can overcome the above defects has become a technical problem to be solved urgently by those skilled in the art.
